This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X1190S, with the same bore, stroke, output force, port and mounting, so it fits the same application. The SAU replacement uses the same profile body, bore, stroke, force and SC-series mounting. It moves to the current CMSG / DMSG / EMSG sensor switches (the SU used CS1-B / DS1-B) and adds the SAUF valve-integrated option.
Airtac SU32~50 Standard Cylinder SU50X1190S
The AirTAC SU32~50 Standard Cylinder SU50X1190S is a double-acting profile-type standard cylinder with a Ø50mm bore and 1190mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X1190S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X1190S
The AirTAC SU50X1190S is a discontinued double-acting profile-type cylinder with a 50mm bore and 1190mm stroke. It delivers 982N push force at 0.5MPa via a 1/4" port. The direct replacement is the SAU50X1190S, matching the bore, stroke, force, port, and SC-series mounting exactly.
This 1190mm stroke exceeds the 1200mm standard maximum and requires external guiding to prevent rod bending. The -S magnet worked with legacy CS1-B/DS1-B switches, but the SAU replacement uses current CMSG/DMSG/EMSG sensors. The SAU line also adds a SAUF built-in-valve option the SU lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X1190S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 N | — |
| Max (@1.0 MPa) | 200 kgf | |
The SAU50X1190S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Legacy SU-family variants: SUD (double rod), SUJ (adjustable stroke) — each maps to its SAU equivalent (SUD→SAUD, SUJ→SAUJ). The current SAU line adds the SAUF valve-integrated option.
Where the Airtac SU32~50 Standard Cylinder SU50X1190S Is Used
Long-Reach Diversion
Pushes packages across a wide conveyor belt using the 1190mm stroke, relying on external guides to prevent rod bending.
High-Bay Extraction
Extracts totes from deep racking where the 982N push force at 0.5MPa easily handles 50kg vertical loads with margin.
Large-Part Transfer
Moves bulky components between machining stations, requiring external load supports due to the nonstandard length.
Replacing the Airtac SU32~50 Standard Cylinder SU50X1190S with the SAU50X1190S
To replace the SU50X1190S, order the SAU50X1190S. Confirm the 1/4" port, M16x1.5 rod thread, and SC-series mounting. Because this 1190mm stroke is nonstandard and long, you must use an external guide to prevent side-load and rod-bending. If sizing down, a 40mm bore gives 628N [email protected]; sizing up, a 63mm bore gives 1559N. The -S magnet means your legacy CS1-B/DS1-B switches must change to CMSG/DMSG/EMSG on the SAU. A plain cylinder drifts without air; use a rod lock for load holding. Consider the SAUF variant if you need a built-in valve.
Replacement checklist
- ✓ Same bore / stroke → SAU50X1190S
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S): sensor family CS1-B → CMSG
- ✓ Mounting reused (FA/FB/CA/CB/LB)
- ✓ Need a built-in valve? → SAUF
Airtac SU32~50 Standard Cylinder SU50X1190S FAQ
Yes, the SU50X1190S is discontinued. The direct replacement is the SAU50X1190S. It matches the 50mm bore, 1190mm stroke, 982N force, 1/4" port, and SC-series mounting, so it fits the same application.
At 0.5MPa it pushes 982N and pulls 825N; at 0.7MPa it pushes 1374N, with a 200kgf max at 1.0MPa. The -S magnet used legacy CS1-B/DS1-B switches, but the SAU replacement requires current CMSG/DMSG/EMSG sensors.
